Specification of Letters Patent.

Patented Dec. 31, 1912.

Application filed April G, 1912. 'Serial No. 685,066

This invention relates to improvements in cloth shearing machines, and has particular reference to a guard for the cutters therefor.

The principal object of the invention is to provide a simple guard plate to protect the hands of the'operator from contact with the shearin blades.

Other obgects and advantages will be apparent fromv the following description and with particular reference to the accompanyingv drawings.

In the drawings Figure l is a front elevation of the shearing cutter blade showing the adjacent portions of the frame of the machine to which the cutter is attached, Fig. 2 is a vertical transverse section on the line 2-.2 of Fig. 1,-and Fig. 3 is a perspective view of the guard detached.

Referring particularly to the drawings, l0 representsgthe frame of` theshearin machine, in which is rotatably mounte the cutter l1, said cutter being mounted on a vertically moving frame 12, and adapted tobe raised and lowered byv means of the'- handles 13. Secured to the frame by means f of the braces 14 is an elongated plate l5.'

Hin edto the lower longitudinalfedge 16 late is a movable 'portion-'17 the lower e ige portion of which is .turned upof the cutters.

wardly as indicated at 18, the saidturned up portion having an elongated slot practically the entire length thereof as indicated at 19, said/slot being adapted for insertion of a sheetof paper for testing the operation 0n each end of the pivoted portion of the plate is arranged a handle 19', which the operator may 'grasp to arrange the movable portion of the plate to 50,*`

gain access tol the cloth in adjusting the maor error in the work of the machine. It sometimes happens that when the o chine, or' in the event of some unevennessg: "i

of the cutter to raise the same and permit? the seam of the cloth to pass thereunder, he,

erator makes asudden reach for' the handleia:

fails to'gmsp the handle and his hand comes* i",

in Contact with the cutter, whichseriously' injures` the hand if it does not completely remove `the fingers. Now my invention is' particularly designed to overcomethis diiiiculty and protect the hands of the operator,

so that should he miss the handle when suddenly reaching for the same, his hand would come in contactwith the` guard plate and n o injuries result.

What is claimed is: *Y A11 attachment for cloth shearingmachines comprisinga guardv latea'igidly and detachably mounted over t emitter-o they' machine 'and a hinged plate forming 'than of the guard, said' hinged platev having fanjj upturned lower edge portion providedwit-h an elongated slot. :f p In testimony whereof, I aa my signa@ ture, in .presence of two witnesses.
